Not nearly as exciting as the last update, but some small progress was made.

Re-arranged the driver code so that more work happens in driver. This should result in a lot less thunking from user space to kernel space, and honestly, it's just the right way to do it.

Roughed in some switch matrix handling code. Doing this is what precipitated the driver rework. Should be able to have a working switch matrix "simultation" early this week.

Made a trusty checklist of what needs to happen for "in machine" testing of switches. If all goes well, I could get to that this week (short week of work means more time to hack pinball!)

Did a little research on my display frame rate issues. Might be able to make some changes to thread priorities, but the rate I'm getting is actually just fine. In fact I have plenty of leeway while still being functional, which is good as there are a lot of mechanics still to code.

Set a simple roadmap to a minimal useable table. I think I should be able to reach that goal by the end of December. The roadmap, in short is: read switches, fire solenoids, code in simple game engine to hook switches to solenoids.
